Quality wood pellets keep house or cottage warm during cold winter.Wood pellets are usual fuel in Europe and in other countries to heat houses and cottages. But the buyer should know about some peculiarities for this kind of firewood.The technical requirements extend on a chemical compound, geometry, mechanical properties, heat ability of wood pellets, the maintenance of micro impurity.
The low power automated boilers are applied to warm small apartment houses or cottages. These boilers have function with for a long time, from 1 week till one month in an automatic mode, without any service.The feeding of fuel is accomplished from the big bunker located, as the rule, in a cellar of a building consisting of the many screw conveyers. The ash which contains in fuel, complete spoils a boiler torch, a grid-iron, the cindery holding chamber. Thus the capacity decreases, and then burning process completely ceases. The interval between stops of a boiler and its clearing depends from wood pellet ash.
Therefore the ash content is the defining factor for boilers which heat small apartment houses or cottages.The wood pellets are loading to the bunker by pneumatic driver of the standard sizes (60-80 mm). The small diameters screw conveyers are applied for feeding from the bunker. The sizes of wood pellets should allow work steadily the pneumatic transport and screw drivers. Thus, the more the size of a wood pellet means superior productivity of a line.
The wood pellets meet considerable mechanical loading while putting into the bunker, and during the task of screw drivers that is why the insufficiently strong wood pellets can collapse. The wood pellets can collapse during storing. It happens due to costly layer of wood pellets make pressure on the bottom layer of wood pellets and insufficiently strong pellets can collapse. During transporting of the wood pellets, the differences of humidity and air temperatures in wood pellets develop internal pressure can easily destroy a pellet too.
There are other indicators of quality, such as humidity and heat capacity. For example, smaller heat capacity speaks about high humidity or much ash content in wood pellet. In turn mugginess doesn't allow receiving sufficient durability of wood pellets.
If you 'd like to be warm during the cold winter in your own and remain your heating system work proper, please a quality of wood pellets you buy in your grocery. Low cost and grey pellets look ok in price but they will force for you to definitely do repair of one's heating system. And throughout colds you will not be able have fun with the warm convenience of your house.
